Positron emission tomography-computed tomography (PET-CT) with both anatomic and functional information is now widely utilized for most lymphoma subtypes,among which,the pretreatment staging and response assessment of PET-CT in Hodgkin lymphoma (HL) and diffuse large B-cell lymphoma (DLBCL)have been well documented.Multiple clinical trials are ongoing using PET-CT for therapy monitoring.Additionally,factors interpreting interim PET (PET-i) like visual analysis using Deauville 5-PS,metabolic tumor volume at baseline (MTV0),and △ SUVmaxPET0-i show different prognostic values.However,the management of PET-CT in lymphoma is still elusive,further trials remain to be done to get evidences for the use of PET-CT in guiding therapeutic decisions.

Objective To summarize our operational experience in using unusual renal allografts.Methods The plastic operations of 326 unusual renal allografts were retrospectively and the renal transplant outcome was compared with 542 normal renal allografts an the same time. Results All the 326 unusual renal allografts were utilized. There was no significant difference between unusual renal allografts and usual ones in average serum creatinine level, acute tubular necrosis (ATN) and the survival rate of renal allgraft after 1 year. There was no complications related to plastic operation during or after kidney transplantation.Conclusions By making good use of various kinds of plastic operation, abnormal or injuried renal allografts can also be used safely without affecting the outcome after renal transplantation.

Objective:To introduce the clinical application of the coil-spring utility arch for orthodontic treatment. Methods:A 35-year-old male patient with mild skeletal anterior crossbite was treated by fixed appliance combined with coil-spring utility arch for 16 months. Cephalometric analysis was conducted before and after treatment.Results:After treatment, the patient's appearance was improved,and the cephalometric analysis showed that SNA increased by 2?,SNB decreased by 1?,ANB increased by 3?,U1-NA increased by 1?,L1-NB increased by 3?.Conclusion:Coil-spring utility arch can expand anterior dental arch continuously and stably.

Objective:To evaluate the effects of different enamel conditioners in combination with an adhesive on the shear bond strength and the adhesive remnant index in vitro.Methods:One hundred and eight permanent healthy premolars from orthodontic patients and fresh saliva from a healthy young volunteer were collected.The teeth were cleaned,dried and etched by phosphoric acid,polyacrylic acid or Transbond plus SEP respectively(36 teeth for each agent).Then the teeth were bonded to brachet by RMGICs with the presence of water,saliva on the tooth surface or without any of them respectively(12 teeth in each group).After bonding,all samples were tested on a testing machine of Instron.Shear bond strength and adhesive remnant index were recorded.Results:Highest mean shear bond strength was observed in the group of teeth etched by Traspond plus SEP and bonded by RMGICs with the presence of saliva.Higher mean shear bond strength was obtained with the presence of saliva or water on the tooth surface than without any of them.Conclusion:Transbond plus SEP conditioning followed by RMGICs bonding may produce high shear bond strength between moistured tooth surface and brachet.

Objective:To study the dynamic frictional resistance in the buccal segment between preadjusted brackets coupled with different archwires,at different times under artificial saliva condition.Methods: The dynamic friction of different combinations of 4 kinds of preadjusted brackets and 4 archwires were tested simulating archwires sliding in the buccal segments at 4 different times(0,15,30,45 d)under artificial saliva condition by using Instron universal testing machine.Results: The dynamic frictional resistance of combinations of 3M MBT bracket and all archwires were the smallest.The combinations of 0.46 mm inch stainless steel round wire and all brackets produced significantly lower dynamic frictional resistance than that of other archwires.The 0.48 mm?0.64 mm inch stainless steel rectangular wire produced the highest dynamic frictional resistance combined with all preadjusted brackets.The dynamic frictional resistance of combinations of archwires and brackets were highest at the 15th day and smallest at the 30th day under artificial saliva condition.Conclusion: 0.46 mm stainless steel round wire produces the smallest dynamic frictional resistance combined with all preadjusted brackets.3M MBT brackets are more favorable to sliding mechanics compared with other brackets.As for time,the lowest dynamic frictional resistance exhibits at the 30th day under artificial saliva condition.

20% ) were assigned to 2 groups according to study intervention: group A ( n =72) receiving DFPP and group B ( n =41) as controls.Group A was subdivided into 2 groups:group A1 ( n =44) was treated by DFPP alone and group A2 ( n =28) was treated by DFPP plus Dac.The incidence rates of HAR,AR,adverse reaction,patie nt/kidney survival,kidney function were observed. All the patients obtained a fo llow-up ≥12 months. Results In 72 patients of group A ,the level of PRA decreased from (60.5?17.7)% to (19.3?11.2)%,with a mean of (41.2?16.9)% ( P 0.05),with 1 kidney-year survival of 94.4% in group A and 78.0 % in group B ( P 0.05);those of AR were 36.4% and 14.3%,respectively ( P 0.05).No difference in infection episodes an d adverse events between group A and PRA-negative recipients, the same as those between group A1 and A2. Conclusions DFPP can decrease the level of PRA significantly before transplantation by selectively eliminating the sensitive antibody,especially when combined with Dac,which can make sensiti zed recipients get the chance of transplanting and further reduce the incidence of AR.The patient/kidney survival rates of 1 year are satisfactory.Being well to lerated by the sensitized patients,treatment of DFPP combined with Dac is safe a nd effective.

Chronic lymphocytic leukemia (CLL) is a kind of malignant B-cell chronic lymphoproliferative disorder with highly heterogeneous clinical courses. Due to the recent advances in immunology, cellular genetics and molecular biology, several prognostic markers based on genetic, phenotypic, and molecular biology characteristics of CLL cells have emerged in the past decade. This article reviews the reports from the 57th American Society of Hematology (ASH) annual meeting on the progress of the prognosis of CLL.

Chronic lymphocytic leukemia (CLL), the most frequent form of leukemia in Western countries, is characterized by the clonal proliferation and accumulation of neoplastic B lymphocytes in the blood,bone marrow,lymph nodes and spleen.During the past decades,important advances have been made in the understanding of the biology,pathology,diagnosis and treatment of CLL.In the 53rd ASH annual meeting,lots of new discoveries about the biology, prognosis, and treatment of CLL were introduced which lead us to further understand CLL and may provide more or better treatments for CLL patients.

Objective To study the tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) expressed in invasive pituitary adenomas (IPA). Methods The expression of TNF-α and IL-6 were observed with immunohistochemstry (SP approach) in tissue from 40 cases of non-invasive pituitary adenomas (NIPA) and 40 cases of IPA. Results The expression of both TNF-α and IL-6 was significantly increased in the IPA tissues compared with those of NIPA (P<0.05). Conclusion TNF-α and IL-6 may play a role in the occurrence and development of IPA.

Objective To elucidate the clinical features of nutcracker syndrome complicated with IgA nephropathy (IgAN) and to increase its level of diagnosis and treatment. Methods Clinical data of 14 cases of nutcracker syndrome complicated with IgA nephropathy (patient group) and 36 cases of nutcracker syndrome (control group) were analyzed retrospectively. Nutcracker syndrome was diagnosed by ultrasonography and magnetic resonance angiography (MRA) and IgAN by renal biopsy. Differences of clinical data and images in two groups were analyzed. Results Gender, age and blood pressure of two groups were not significantly different. Higher Scr level [(81.2±21.3) μmol/L vs (61.2±11.8) μmol/L, P<0.01], more severe proteinuria [(1.1 ± 0.6) g/d vs (0.3±0.2) g/d, P<0.01] and hematuria (2.3±0.9 vs 1.5±1.3, P<0.05) in patient group were found. Differences of ultrasonography and MRA in two groups were not significant. Conclusion Renal biopsy should be considered in cases of nutcracker syndrome with persistence of proteinuria, hematuria or abnormal morphology of urinary red blood cell.
